SPECIFICATION forming part of Letters Patent No. 65 7,5Q9, dated September 11, 1900.

Application filed J'une 19, 1899. vSwirial No1` 721,172. (No model) To (LZZ whom it may con/cern:

Be it known that I, REUBEN C. BRUBAKER, a citizen of the United States, residing at El `Dorado, in the count-y of Preble and'State of Ohio, have invented `certain new and useful Im provementsin Harvesters; and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present in vention relates to harvesters; and the principal objecti-s to provide a construction of master- Wheel and modeof mount` ing the same which will permit of Vthe cut grain being taken through the wheel instead of over the same to the binder. By such an arrangement. I obtain the advantage of lessening the angle of the elevating portion of the apron, so that a cover-apron can be dispensed with, and besides this Iam enabled to make the machine more compact than the usual form of harvesting mechanism and better adapted for attachment of the binder, While at the same time itis feasible to employ a greater numberof packers than heretofore Incidental objects are to arrange for the translnission of power to the various moving" parts of the` mechanismA from .the master# Wheel in a simple and practical manner and to automatically.compensate for variations in the relative positions of the main frame and the supports for the inclined portion of the traveling apron, the main frame being vertically adjustable and. gearing connecting a line-shaft on.such frameowith anapron carrying a roller whose position remains practically the same under all adjustments of the frame, so as not to disturb its proper relation to the binding attachment. i t

With the above-stated objects in view the invention consists in certain novel features of construction and combinations of parts,- theessential elementsof which are recited in the appended claims, and a preferred form of embodiment is specifically described hereinafter and illustrated in the accompanying drawings, which form a tion. i Y

`.Of said drawings, FignreI represents the complete machine in perspective., `Fig.II is a sectionalized side elevation of the same. Fig. III shows a lpartial front `elevation with `imity `to the masterwvheel.

partof this specifica-v certain parts broken away and others appearing in cross-sectionf Fig. IV shows the master-wheel and its ring-bearing in side elevation, together with certain gearing for adjusting the main frame. Fig. V shows the same parts in vertical cross-section, together with a portion of the main frame and certain parts supported thereby. Fig. VI is a fragmentary end elevation showing the grain- Wheel, and Fig. VII is a vertical section of the same.

The master-wheel comprises a broad rim ct, with a circular internal .gear a' at the outer side and a centrally-located internal rib d2.V

Thebearing for `this master-wheel is in the form of a ring b, whichV is slotted at various points throughout its circumference to accom modate antifrictionrollers b', grooved for engagement with the rib a2, as clearly shown in Fig. V. This ring-bearing maintains practically a iixed position in the machine, and

those of its rollers'below a central horizontal line are preferably somewhat larger than those above, with a view to more elfectually sustaining the superimposed weight which must `be borne by this ring-bearing, as will presently appear. i i. t

The main frame of the machine 1s of generally rectangular-form and comprises front t and rear bars c and c-, extending on either side of themaster-wheel, end bars o2 andjcs, and intermediateV cross-bars c4 and c5 in prox- A shaft d is supported in brackets CZ', fastened to the said cross-bars c4 and c5, and said shaft carries a pair of pinions d2, which engage racks d3, fastened to the ring-bearing b, the lowercentral portion of the latter being widened and slotted for theA passage of said shaft, and the said racks being formed. upon brackets b4, secured tol said widened portion of 'the ring and projecting somewhat above the same and formed with slightly-curved'slots b5 to accommodate the shaft d, the said curvature be- `ing provided: for a purposet be more fully hereinafter explained. It will beseen that by turning the pinions d? the frame can `be raised and lowered by reason of the travel of said pinions along"V the racks, and means of the following description'are vprovidedfor-the purposeof eecting suchadjustmentsof the frame:

Of course downward movement of the main frame results in a partial straightening of the toggle and re.-`

tracting of the roller r.

Segm en tal plates y are preferably fastened to the ring-bearing b and overlapthe master, wheel gear, so as to prevent the entrance therein of foreign matter which might clog the gears, the outline of the lower edge of one of said plates being indicated by dotted linel Y y in Fig. IlV and the two plat-es appearing in ,cross-section in Fig. III.

and main frame are preferably connected by brace-ba rs no, (see Figs. II and IIL) one on each side of the master Wheel and pivotally attached to the parts they connect.

The purpose of the curved slots b5 will now The shafts g' and d and the` points of the frame atwhich the links a: are .attached are fixed relative to each other, and

be apparent.

by reason ofthe curvature of the said slots b5 the gear g2 remains in engagemen twith the l internal gear a during all positions of the` main frame.

In order to prevent the lower stretch of the elevating portion of the endless apron from interfering with the gearing for raising `and lowering the frame, an angular guard-plate w may be fastened to the cioss-barc5,as shown in Figs. IV and V.

It will be seen that a harvester constructed .as above described is peculiarly well adapted for coupling with a binding attachment, there being no mechanism to offer an obstruction to such attachmentat the upper end of the elevator. It will also be seen that by reason of the elevating portion of theV apron passing through the master-wheel instead of over the same not so great an elevation is required and the grain will be carried `up the same Moreover, the arrangement of a large portion of the operating mechanism` within the circle of the master-wheel resultsA more easily.

in a compactness of construction, which Vis an obvious advantage. u j

It is of course to be understood that the invention herein described may be embodied in other forms than here shown without departing from the spirit and scopetlheleof, and

hence I do not desire to limit myself to the.

constructive details.
